Re: EVGA GeForce GTX 950 2 GB

While I am no expert, some general suggestions. Firstly, Leela specifically benefits from some optimizations known as "fp16", which roughly triples the speed in nps. The newer RTX 20XX series cards support this. The older 10XX cards do not. A value-priced option instead of the 2080ti would be a 2060...

Now type "go wtime 5000" and hit enter. If it does a little search then your all ready to install into your chess GUI.
Perhaps you meant go "movetime" 5000" instead of "wtime".

It is playing fine under Winboard.

Is there a specification for the file format used by Syzygy which could be used to independently write probing code?
Yup. Right here:

Re: Chess Fighter Neural Net release

I am no UCI expert, but it might not matter if the engine makes the moves as the GUI will send the position and an appropriate move list each time anyway, I think. Was having some trouble under Arena. Tried under Winboard. Does run, but moves instantly. Have go head off to work. Will look at it agai...

Re: Chess Fighter Neural Net release

Tried with Win7. Had to copy cudart64_92.dll and cublas64_92.dll into the directory. Always searches for around 38,000 nodes for me, regardless of go <w,b>time n command Appears to be making the moves, which should not be done. Some --help info would be, well, helpful. A very good start. Did you use...

Re: Super bullet chess: LC0 v0.21.0 network 41619 vs newest Stockfish dev 200319

With Ponder On and SF getting 4 cores, and Leela typically using 2 cores, just wondering if this was a 6 core system?
Thanks.

Re: On-line engine blitz tourney March

Just wondering if Leela was playing the 6 piece syzygy tablebases, which improve her endgame play far more than traditional a/b engines? I assume there was no book. Thanks. 5 piece syzygy tablebases and an opening book. Was the book made specifically for Leela? If not, it is a significant handicap ...

Re: Help with Leela and graphics cards

I am no expert, however this issue has come up several times before. For Leela no SLI is needed (and might hinder performance). The Nvidia libraries handle multiple GPUs automatically, although you have to specify that you want to use both with some parameters. For some games, I think the SLI IS hel...

Re: Creating a spoon of TSCP181

To avoid problems with spooning a non-free engine, I might be tempted to create a very basic bitboard engine. Interested? For me, I would follow you with interest, if it really is very basic as you promise. :) I started here a discussion where I try to understand the basics of bitboards. I would li...
